Example Usage

import { applyEasing, EASING_ID, EasingFnIdsVL } from '@hypericon/easy';

const from = 0;
const to = 200;
const duration = 100;
const easingFnId = EASING_ID.inOutCubic;
const easingName = EasingFnIdsVL.find(vl => vl.value === easingFnId)?.label ?? "[unknown]";

console.log(`Ease from ${from} to ${to} over ${duration} steps using ${easingName}`);

for (let t = 0; t <= duration; t++) {
  const v = applyEasing(easingFnId, duration, t, from, to);
  console.log(`t: ${t}, v: ${v}`);
}
